alter working 4 hours, frank has made 21 machine parts.at the same rate how many parts can he make in 7 hours? 4(21)/7,7(21),7(21)/4,7(4)/21,7(4)(21)?

- 3For a machine with an efficiency of 80%, what is the work output of the machine if its work input is 2,000 joules
For a machine with an efficiency of 80%, what is the work output of the machine if its work input is 2,000 joules? would i divide 2000/.80? which gives me 2500?

- 4percentages:
to use a machine,u must do the work on the machine called input work
percentages: to use a machine,u must do the work on the machine called input work. the machine then foes the work on and object called output work. not all the input work gets transmitted to output work. some work is lost due to friction in the machine. if a machine has an input work of 250 joules and 25% of the input work is lost due to friction, what is the output work of the machine.
